It all started with a Milkshake in Purcell, OK Traditional Cache

In 1954, Ray Kroc, a seller of Prince Castle brand Multimixer milkshake machines, learned that the McDonald brothers were using eight of his machines in their San Bernardino restaurant. His curiosity was piqued, and he went to take a look at the restaurant. He was joined by good friend Charles Lewis who had suggested to Kroc several improvements to the brother's burger recipe.

Believing the brother's formula was a ticket to success, Kroc suggested they franchise their restaurants throughout the country. The brothers were skeptical, however, that the self-service approach could succeed in colder, rainier climates; furthermore, their thriving business in San Bernardino, and franchises already operating or planned, made them reluctant to risk a national venture.Kroc offered to take the major responsibility for setting up the new franchises elsewhere. He returned to his home outside of Chicago with rights to set up the restaurants throughout the country, except in a handful of territories in California and Arizona already licensed by the McDonald brothers. The brothers were to receive one-half of one percent of gross sales. Kroc's first  restaurant opened on April 15, 1955, at 400 North Lee Street in Des Plaines, Illinois, near Chicago ;- and the rest as they say "Is History."

This is an easy Park and Grab but I thought I'd give you a little history you maybe didn't know about.
